Main Rotor Head Replacement Part for WLtoys K150 AS350 RC Helicopter

Restore Your Core Flight Stability

Is your WLtoys K150 vibrating excessively or struggling to maintain a steady hover after a minor impact? The rotor head is the heart of your helicopter's mechanical system, and even microscopic bends or wear can compromise the 6-axis gyro's performance. This original replacement rotor head solves flight instability issues by providing a perfectly balanced and rigid hub for your blade grips, ensuring your AS350 Squirrel returns to its factory-smooth flying characteristics.  Ships worldwide.

Product Highlights

• Precision Balancing: Engineered with tight tolerances to ensure zero-vibration rotation, which is critical for the high-RPM demands of brushless motors.

• Reinforced Durability: Constructed from high-impact composite materials to resist deformation during aggressive 4-channel maneuvers and soft landings.

• Perfect Geometry: Features exact mounting points for the spindle shaft and blade grips, maintaining the correct mechanical phase for the AS350 scale model.

• Lightweight Efficiency: Designed to minimize rotational mass, allowing for quicker throttle response and extended battery life for your K150.

What’s in the Box

• 1 x WLtoys K150 RC Helicopter Rotor Head

Install Tips

• Main Shaft Attachment: Slide the rotor head onto the main shaft and ensure the cross-hole aligns perfectly before inserting and tightening the retaining screw to prevent vertical play.

• Blade Grip Mounting: When attaching the blade grips to the rotor head, ensure the bearings are seated correctly and that the grips pivot smoothly without sticking.

• Screw Security: Use a small drop of non-permanent thread locker on any metal-to-metal screws (like the spindle shaft bolts) to prevent them from vibrating loose during flight.

• Final Balance Check: After installation, spin the rotor head by hand without the blades first to check for any visible wobbling in the main shaft assembly.

Support & Warranty

• 3-month warranty on manufacturing defects
• Ships worldwide
